ABSTRACT
We report the technical success rate and mid-term follow-up results after deploying stent-grafts to treat a cohort of patients with symptomatic complicated intra- or extracranial aneurysms (SCIEAs). This study was a retrospective review of 58 patients (39 male; mean age 40.4 ± 12.3 years) with 60 SCIEAs treated by 67 Willis covered stents at three medical centers in China between April 2005 and January 2010. The locations of the SCIEAs were as follows Intracranial internal carotid artery (ICA) in 54 patients, extracranial ICA in one, intracranial vertebral artery (VA) in three and extra-cranial VA in two. Surgery was successful in 59 (98.3%) SCIEAs. Total exclusion was immediately achieved in 48 SCIEAs, and minor endoleaks were present in 11. Acute thrombosis occurred in two patients and hemorrhage in one. Follow-up angiography (mean 13.8 ± 8.9 months) revealed that 49 of 52 (94.2%) aneurysms were completely isolated, with mild in-stent stenosis in only two patients and in-stent occlusion in one patient. Willis stent-graft application is an alternative therapy to treat SCIEAs in either intra- or extracranial ICAs or VAs. In the case of a tortuous intracranial ICA or potential side branch coverage, however, it is still not a first choice.
